Definitions
- MDU multi-dwelling unit
- service provider cables entered an MDU building by, for example, a basement through means of an entrance facility. These cables and associated equipment were often installed and terminated at a central location, such as a dedicated telecommunications room from which building distribution wires, often cables in building distribution conduits, distributed the service to customers in living units throughout the building. Service provider personnel thus are required to access both the dedicated telecommunications room and the customer living unit in order to install the wiring required to provide service to the customer.
- the building owner or developer may choose to provide access to this inside wiring through means of a single modular jack on a unit distribution panel in the living unit that distributes up to four communication services throughout the living unit.
- the customer then allows a single service provider personnel to connect service to the unit distribution panel jack.
- FIG. 1 is an example of a MDU building system.
- FIG. 2 is an example of a Category-5 cable termination to a RJ-45 type plug connector, shown as a break-away diagram.
- FIG. 3 is an example of a distribution panel
- FIG. 4 is an example of a unit distribution panel and an interface.
- FIG. 5A is a pictorial view of an embodiment of an interface.
- FIG. 5B is a schematic diagram of line parings between interface input jacks and interface output jacks.
- FIG. 6 is an alternative embodiment showing a schematic of an interface arranged with a matrix-like pattern of interface input jacks.
- FIG. 1 shows an exemplary system 100 to enable service provider access to pre-installed living unit inside wiring, such as unit distribution wiring 205 of living units 212 of a MDU building 200 .
- Telecommunication service providers may deliver various services to the building by copper wire, fiber optics, satellite, free space optics or other transmission capabilities, as represented by cables 201 in FIG. 1 .
- Cables 201 enter building 200 through the basement.
- a building distribution panel 202 terminates cables 201 and routes signals to individual living units 212 in building 200 via distribution wiring, such as building distribution wiring 203 .
- Some buildings also route doorbell 209 or concierge services to building distribution panel 202 for distribution to living units 212 via distribution wiring.
- Distribution wiring can enter an individual living unit 212 and can be directly routed throughout the living unit or, as shown in FIG.
- building distribution wiring 203 can be routed to a unit distribution panel 204 in a service closet 211 . Signals from building distribution wiring 203 are coupled via unit distribution panel 204 to unit distribution wiring 205 .
- Unit distribution wiring 205 terminates at service outlets 210 installed at locations in the living unit such as a family room, bedroom, or office. The customer may then connect a device such as a computer 208 , telephone 206 , television 207 , or router (not shown) to service outlet 210 to obtain service on that device.
- Unit distribution wiring 205 may be provided in the form of shielded or unshielded cable such as twisted-pair, Category-3, Category-4, Category-5, etc.
- the cable of unit distribution wiring 205 is made up of multiple pairs of wires.
- Telecommunication services are typically provided using a single pair of wires, though some services, such as doorbell service, are capable of operation on only one wire of a cable.
- FIG. 2 shows a break-away diagram of an exemplary Cat-5 cable termination to an RJ-45 (Registered Jack) type plug connector 224 .
- Cat-5 cable has four pairs of wires 220 with ends 221 that electrically connect to eight respective connector terminals 222 of connector 224 .
- Wires 220 are connected to the connector terminals 222 according to an industry-standard pattern such as 568A, 568B, or USOC, though a straight-line connection has been shown in FIG. 2 .
- Many service providers use only the center two connector terminals 222 at positions 4 and 5 of the connector 224 .
- FIG. 3 shows a detailed view of a unit distribution panel 204 .
- Building distribution wiring 203 terminates at unit distribution panel 204 .
- Unit distribution wiring 205 also terminates at the distribution panel 204 .
- one cable of building distribution wiring 203 terminates to a service provider jack 306 having service provider terminals 307 electrically connected to individual wires of building distribution wiring 203 .
- jack-type (ferrule) connectors have been illustrated on the unit distribution panel 204 , some unit distribution panels 204 may employ plug (male) connectors, or both jack and plug connectors.
- a jumper 310 shown schematically in FIG. 3 , may be used to electrically connect service provider jack 306 to unit distribution jack 308 having unit distribution terminals 309 electrically connected to individual wires 220 of unit distribution wiring 205 . It can be seen that unit distribution panel 204 may have multiple service provider jacks 306 for a single unit distribution jack 308 .
- Unit distribution wiring 205 includes one Cat-5 cable, providing a total of eight wires 220 , with the potential to deliver service from four service providers throughout living unit 212 . However, the eight wires 220 of unit distribution wiring 205 terminate in one unit distribution jack 308 .
- a service provider uses a jumper 310 with RJ-45 connectors 224 to couple service provider signals to unit distribution jack 308 , that service provider effectively blocks access to the remaining wires 220 of the Cat-5 cable of unit distribution wiring 205 . Only one service provider may be connected at unit distribution panel 204 , thereby leaving the remaining service providers with no way to gain access to living unit 212 . This arrangement also leaves six wires of the eight wires 220 of unit distribution wiring 205 unused.
- FIG. 4 shows unit distribution panel 204 of FIG. 3 used with a communication line interface 400 , according to an exemplary embodiment.
- interface 400 includes a plurality of interface input connectors, such as RJ-45 jacks 401 - 404 .
- Interface 400 also includes an interface output connector such as RJ-45 jack 405 .
- Input jacks 401 - 404 are configured to receive corresponding cable input connectors of input cables, such as RJ-45 plugs attached to input jumpers 311 a - 311 d coupled through service provider jacks 306 to cables of building distribution wiring 203 .
- Interface output jack 405 is configured to receive a cable output connector such as an RJ-45 plug attached to an output jumper 312 coupled through unit distribution jack 308 to a cable of unit distribution wiring 205 .
- Service provider signals are transferred from the building distribution wiring 203 , through the service provider jacks 306 , into the input jacks 401 - 404 , across routing conductors, out interface output conductor 405 and back in to distribution panel 204 through unit distribution jack 308 , and onto Cat-5 cable of unit distribution wiring 205 for distribution to outlets 210 .
- interface 400 enables multiple service providers to connect to unit distribution panel 204 in a manner that can utilize all of the wires on unit distribution wiring 205 .
- interface 400 accepts jumpers 311 a - 311 d from four service provider jacks 306 of a unit distribution panel into interface input jacks 401 , 402 , 403 , 404 .
- Interface 400 provides electrical connection of the inputted service provider signals to terminals of an interface output jack 405 using routing conductors, which electrically connect interface input terminals to interface output terminals.
- the routing conductors may comprise discrete wires, printed circuit wiring or another type of conductor.
- a living unit 212 can have a first telephone line Line 1 connected to a jack 306 of unit distribution panel 204 by a first service provider.
- the same service provider, or another, may provide a second telephone line Line 2 connected to a second jack 306 .
- Another service provider could provide an additional service on Line 3 at another jack 306 .
- the doorbell 209 , concierge or yet another service provider could provide a service on Line 4 of a jack 306 on unit distribution panel 204 . All four providers may then be, by jumpers 310 , routed to respective interface input jacks 401 - 404 of the interface 400 , through internal routing of the interface 400 , to interface output jack 405 .
- Line 1 through Line 4 could be occupied by telephone, data, doorbell, or any other services capable of interfacing with Line 1 through Line 4 .
- FIG. 5A shows a pictorial view of interface 400 using all RJ-45 type jacks.
- Other jack types can be substituted with their corresponding differences in terminal numbers. It is also possible to use jack type connectors that can receive more than one type of cable connector.
- the RJ-45 jacks can receive either RJ-11 type plugs or RJ-45 type plugs.
- interface input jacks 401 - 404 can be RJ-11 type
- interface output jack 405 can be RJ-45 type.
- 8P8C type connectors can be used, which can have a corresponding change in wiring pattern at the connector terminals to 568A, 568B, or USOC.
- other numbers of interface input jacks can be used, as well as other numbers of actively used terminals.
- FIG. 5B is an electrical schematic view of the interface 400 .
- Each of jacks 401 - 405 may include eight terminals labeled 1 - 8 .
- the actively used terminals of jacks 401 - 405 are indicated with vertical lines extending upwardly therefrom.
- routing conductors electrically connect interface input terminals with interface output terminals using pairs of routing conductors at each interface input terminal.
- Each interface input routing conductor pair is routed to a corresponding pair of interface output routing conductors at interface output terminals following a predetermined pattern.
- One possible routing pattern is shown following an exemplary 568A pattern at interface output jack 405 .
- Each active terminal at positions 4 and 5 of respective interface input jacks 401 - 404 is routed to a respective separate terminal on interface output jack 405 .
- Line 1 of interface input jack 401 is routed as PAIR 1 to interface output terminals 4 and 5 .
- Line 2 of interface input jack 402 is routed as PAIR 2 to interface output terminals 3 and 6 .
- Line 3 of interface input jack 403 is routed as PAIR 3 to interface output terminals 1 and 2 .
- Line 4 of interface input jack 404 is routed as PAIR 4 to interface output terminals 7 and 8 .
- FIG. 6 shows a schematic of an alternative embodiment, using an interface 500 having a matrix-like pattern of interface input jacks 501 , 502 , 503 , and 504 .
- Interface output jack 505 is distinguished in position from interface input jacks 501 - 504 .
- Other arrangements and configurations of input jacks and output jacks may be contemplated to accommodate different sizes or shapes of connectors, or to accommodate space, mounting, or stability requirements near unit distribution panel 204 .
- Interface 400 may also have more than one interface output jack to correspond to a larger number of unit distribution jacks 308 on unit distribution panel 204 .
- This multi-output interface would have a corresponding multiplicity of interface input jacks organized to optimize wire usage on each cable of unit distribution wiring 205 .
- Unit distribution wiring 205 may also comprise more than one cable, and more than one type of cable, with a corresponding change in the number and type of unit distribution jack 308 . In this embodiment, either a multi-output interface would be needed, or multiple interfaces would be needed, each with corresponding interface output jacks 405 .
- MDU building has been shown and described, a high-rise or a sprawling MDU building, stand-alone dwelling, town home or other structure can also benefit from the interface described herein. Though living units have been shown and described, the interface can also be used in business settings.
- the interface 400 can be used with entrance facilities, telecommunication rooms, communication nodes, closets or hotels, and the interface can be used at distribution panel 202 .
- Other types of distribution panels 202 and 204 are also contemplated, including distribution panels that do not have service provider terminations or jacks 306 .
- a service provider routes building distribution wiring to a living unit 212 and connects to interface 400 , which is connected to a unit distribution jack 308 .
- a service provider routes cables 201 to a building 200 and connects to interface 400 , which is connected to a building distribution jack on a distribution panel 202 .
